I have some camcorders that do not have "night shot" or a built-in infrared lamp. If I get an external IR lamp will these camcorders be able to detect it? They're all Panasonics--SDR-S26, SDR-S26K, SDR-H85, HDC-HS250P, and PV-GS250.
Answer
yes and no. All normal camcorders and digital cameras can detect IR light. For that reason they all have IR blocking filters to prevent having false colors in normal conditions. In a few models, the filter can be defeated to create "nightshot" effects, but not the Panasonics. Some hackers are willing to do surgery on their camera to forcibly and permanently remove the filter that is located on the CCD sensor. not really a good idea. some cameras have a poorly functioning filter and pickup some IR light. to test yours, point a television remote control at the camera lens and see if there is a light when the buttons are pushed.

camcorder shutter speed for low light conditions?
leatricema
There is a shutter speed given for video cameras in low light conditions. (1/30, 1/60, etc.) Is this the speed of the lens at all times or just when the lighting is low?
Answer
The camcorder's shutter speed is in fractions of a second and the amount of time the shutter remains open to allow light to hit the imaging chip (CCD or CMOS).
1/30 is typically the auto setting when in low light. Smaller number in the denominator means the shuttr stas open longer. Moving objects will record with ghost tailing and possibly blurred. 1/60-1/125 is in daylight. In auto shutter mode, as the lighting get brighter (or the aperture is opened), the shutter speed can increase. Most camcorders also allow you to manually set the shutter speed. At about 1/500-1/1000, the aperture can't open any more and the image will darken unless lots of light is added to the scene. Be careful, though, at this speed or faster, there is an irritating "strobe" effect that settles in and can be very uncomfortable for the viewer.
(Remember, still photos capture is different from video - with stills, typically, the goal is to freeze the moment so faster shutter speeds are more common. Which video, motion is fluid, so each frame does not need to have everything in sharp focus).
